Deleting Versioning Objects

If you have any questions during development, post them on the Issues page of GitHub.

Deleting a Single Versioning Object

You can call delete_object to pass the version ID (version_id) to copy a versioning object. Sample code is as follows:

static void test_delete_object_version()
{
    obs_status ret_status = OBS_STATUS_BUTT;
    // Create and initialize object information.
    obs_object_info object_info;
    memset(&object_info, 0, sizeof(obs_object_info));
    object_info.key = key;
    object_info.version_id = version_id;
    // Create and initialize option.
    obs_options option;
    init_obs_options(&option);
    option.bucket_options.host_name = "<your-endpoint>";
    option.bucket_options.bucket_name = "<Your bucketname>";

    // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY.
    // Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
    option.bucket_options.access_key = getenv("ACCESS_KEY_ID");
    option.bucket_options.secret_access_key = getenv("SECRET_ACCESS_KEY");
    // Set response callback function.
    obs_response_handler resqonseHandler =
    { 
        &response_properties_callback,
        &response_complete_callback 
    };
    // Delete an object.
    delete_object(&option,&object_info,&resqonseHandler, &ret_status);
    if (OBS_STATUS_OK == ret_status) 
    {
        printf("delete object successfully. \n");
    }
    else
    {
        printf("delete object failed(%s).\n", obs_get_status_name(ret_status));
    }
}

Deleting Versioning Objects in a Batch

You can call batch_delete_objects to pass the version ID (version_id) of each to-be-deleted object to batch delete them. Sample code is as follows:

static void test_batch_delete_object_version()
{
    obs_status ret_status = OBS_STATUS_BUTT;
    // Create and initialize option.
    obs_options option;
    init_obs_options(&option);
    option.bucket_options.host_name = "<your-endpoint>";
    option.bucket_options.bucket_name = "<Your bucketname>";
    // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY.
    // Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
    option.bucket_options.access_key = getenv("ACCESS_KEY_ID");
    option.bucket_options.secret_access_key = getenv("SECRET_ACCESS_KEY");

    // Initialize information of the objects to be deleted.
    obs_object_info objectinfo[100];
    objectinfo[0].key = "obj1";
    objectinfo[0].version_id = "versionid1";
    objectinfo[1].key = "obj2";
    objectinfo[1].version_id = "versionid2";
    obs_delete_object_info delobj;
    memset_s(&delobj,sizeof(obs_delete_object_info),0,sizeof(obs_delete_object_info));
    delobj.keys_number = 2;
    // Set response callback function.
    obs_delete_object_handler handler =
    { 
        {&response_properties_callback, &response_complete_callback},
        &delete_objects_data_callback
    };
    // Delete objects in batches.
    batch_delete_objects(&option, objectinfo, &delobj, 0, &handler, &ret_status);
    if (OBS_STATUS_OK == ret_status) {
        printf("test batch_delete_objects successfully. \n");
    }
    else
    {
        printf("test batch_delete_objects faied(%s).\n", obs_get_status_name(ret_status));
    }
}
